 READFORMAT()
 Return, and optionally set, the code block that implements a format (.fmt)
 file
------------------------------------------------------------------------------
 Syntax

     READFORMAT([<bFormat>]) --> bCurrentFormat

 Arguments

     <bFormat> is the name of the code block, if any, to use for
     implementing a format file.  If no argument is specified, the function
     simply returns the current code block without setting a new one.

 Returns

     READFORMAT() returns the current format file as a code block.  If no
     format file has been set, READFORMAT() returns NIL.

 Description

     READFORMAT() is a Get system function that accesses the current format
     file in its internal code block representation.  It lets you manipulate
     the format file code block from outside of the Get system source code.

     To set a format file, use SET FORMAT (see the SET FORMAT entry in the
     Reference guide) or READFORMAT().

     READFORMAT() is intended primarily for creating new READ Layers.  The
     code block that READFORMAT() returns, when evaluated, executes the code
     that is the format file from which it was created.
